I see what you're saying, I just don't think many High Fantasy settings have really sat down and considered what can be done practically with that amount of magic. I'll give you some examples using just what we know from TES magic.
- We know Netch are farmed already, so why aren't the Dunmer breeding them for construction of air-ships?
- Why isn't Enchanting industrialized? Especially if even lowly farm animals have souls and can therefore act as a battery?
- Why aren't Fire Atronauchs summoned simply to drive steam engines?
- Where are the large scale Mark/Recall freight transport operations?
- Why aren't there flying steel battleships with rows of constant effect feather/levitate enchantments on their hulls?
I believe these are only a few of the many things that would quickly appear in a high fantasy world. But usually the authors of such worlds are more concerned with "what would the powerful people do with Magic" or "how would Magic affect war" rather than "what would entrepreneurs do with access to that kind of magic"?
Yes, good points.
Of course, reasons can be imagined why those things dont happen.
Magic is still somewhat dangerous and perhaps using a fire atronarch for such a menial task would attract unwanted attention from things higher up the daedra chain?
There is some evidence other races wont use things like Dwemer airships because they view them as 'profane'.
It is very possible that advancement in Tamriel is nothing more than knowledge granted by the gods.
The Dunmer attribute all sorts of things to Boethiah, from architecture to lawmaking.
This may mean that the gods do not like devices such as the Dwemer made, and discourage people from using or developing them.
Maybe the gods have a direct influence on how day to day life is organised, and something like a rat farm for soul traps would be considered profane.
Mark and recall might very well have weight or mass limitations, and distance limitations. We dont know.
We can reasonably say that it cannot be used to transport yourself and a passenger though, as in-lore usage such as the poison song invariably describes it as one person only.
These are all just specualtions though and the real reason probably is that they want a low-tech and magical world.
But postulating why things as they are are logical, I think is a nice way to spend the time
